配置

代理

给 Docker 设置代理，该代理是在拉取镜像时的网络代理设置

mkdir -p /etc/systemd/system/docker.service.d
cat > /etc/systemd/system/docker.service.d/http-proxy.conf << EOF
[Service]
Environment="HTTP_PROXY=http://your.proxy:8080"
Environment="HTTPS_PROXY=http://your.proxy:8080"
Environment="NO_PROXY=127.0.0.1,localhost"
EOF
systemctl daemon-reload
systemctl restart docker

运行时代理

{
        "HttpHeaders": {
                "User-Agent": "Docker-Client/19.03.4 (linux)"
        },
        "proxies": {
                "default": {
                        "httpProxy": "http://172.17.212.62:3128",
                        "httpsProxy": "http://172.17.212.62:3128",
                        "noProxy": "127.0.0.1,localhost,172.17.212.63"
                }
        }
}

Insecure

vim /etc/systemd/system/docker.service.d/docker.conf

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// --insecure-registry 10.101.101.45:5000

vim /etc/docker/daemon.json

"insecure-registries" : ["192.168.0.180"]

Ubuntu 下修改配置文件 vim /etc/default/docker 添加如下内容：

DOCKER_OPTS="$DOCKER_OPTS --insecure-registry registry_server_name/ip:port"

User

让普通用户可以执行 docker

sudo groupadd docker

sudo gpasswd -a ${USER} docker

sudo service docker restart

并发下载（推送）镜像

下面的示例中给出了如何设置（/etc/docker/daemon.json）并发下载或者推送镜像层的配置：

{
	"max-concurrent-uploads": 20,
	"max-concurrent-downloads": 20,
	"registry-mirrors": [
		"https://qtzsrp4m.mirror.aliyuncs.com",
		"https://hub-mirror.c.163.com",
		"https://mirror.baidubce.com"
	]
}

重启服务

执行命令 systemctl daemon-reload && systemctl stop docker && systemctl start docker
